constexpr bool ok() const noexcept;
(since C++20)

Checks if the weekday object and the index stored in *this are both valid.

[edit] Return value

true if weekday().ok() == true and index() is in the range [15]. Otherwise false.

[edit] Example

Run this code
#include <chrono>
#include <iostream>
 
int main()
{
 std::cout << std::boolalpha ;
 
 std::chrono::weekday_indexed wdi{std::chrono::Tuesday [2]};
 std::cout << (wdi.ok()) << ' ';
 wdi = {std::chrono::weekday (42)[2]}; 
 std::cout << (wdi.ok()) << ' ';
 wdi = {std::chrono::Tuesday [-4]}; 
 std::cout << (wdi.ok()) << '\n';
}

Output:

true false false
